Many people who live in houses don't know all that much about their own roofs. If you asked them, they might say all is well if it doesn't leak. One important part of advance planning to keep problems from developing is using a roof closure vent. This system is designed to keep moisture problems from destroying your roofing from underneath.
For those who are clueless about the make-up of their roofs, there are some basic facts that are easily understood. A roof is subject to many stresses. One is extremes of temperature. Actually, painting a metal roof a light color in hot climes and a dark one in cold is the best solution to temperature. Venting has more to do with moisture.
Apparently air inside your house rises into the space under the roof, bringing moisture with it. Warm air holds more moisture than cold. So if warm air rises, and the roofing is cooler, droplets of water form on the underside. If the roofing is vented, outside air flows in and disperses this moisture before it can damage insulation, shingles, or metal.
'Soffit' vents under the eaves of the house let air in. The closure vents higher up let air out. Wind moving across the top of the building is the activator of this exchange. As air flows out, moisture is taken out as well, before it can condense and cause problems of mold, rot, or corrosion. The process of venting a ranch-style home is fairly easy. Modern, many-gabled roofs make the process a lot more complicated.
There is another problem. Openings in roofing are great ways for bugs, birds, small climbing rodents, and the elements (rain and snow) to get inside your attic. Therefore you need vents with screening or baffles to keep them out. Well-designed venting systems keep everything out but air.
Check out the easy-to-install one piece units online if you need to vent an existing structure. They are simply stuck into place using their own adhesive strips. It's easiest to do this kind of installation at construction, when vents can be installed along the ridge of the house. Vents should be made of durable materials and can be guaranteed to last as long as the roofing itself.
Online you will find a lot of information about the value of well-designed vents and the different kinds on the market. You also may see some debate about whether or not you should include vents in your home at all. Many roofs carry a 30-year warranty; check if this guarantee will be voided if you do not vent. It's important to make sure that outside air comes in at the same rate that trapped air is drawn out. Otherwise, air may be pulled from the home's interior, which will raise your energy costs.
So the main idea is simple. Get hot, wet air out and let cooler, dryer air in on a continuous basis. At the same time, keep creepy crawlies, flying things, and rain or snow out without interfering with the desired air flow. Fortunately for homeowners, there are products on the market designed to do both with maximum efficiency.
